UNITED STATES PATENT OFFICE THEODORE OREIGIITON, OF TIFFIN, OHIO.

INSULATOR.

SPECIFICATION forming part of Letters Patent No. 450,708, dated April 21, 1891.

Application filed June 19, 1890. Serial No. 355,917. (No model.)

To all whom it may concern:

Beit known that I, THEODORE OREiG-HTON, a citizen of the United States, residing at Tiffin, Seneca county, Ohio, have invented a new and useful Improvement in Insulators, of which the following is a specification.

In the drawings forming a part hereof, Figure 1 is an elevation of the insulator, and Fig. 2 is a longitudinal section of the same.

The insulator herein described is preferably integral respecting all its parts and composed of glass or other non-conductor of electricity. It is intended for use in connection with telegraph Wires, lightning rods, and other similar purposes. It is formed with a screw-threaded stem a, by which it may be fastened to a pole or other support in the well-known manner, storm-shield b, annular groove 0, in and around which the wire is to be wound and a hole or aperture 8, through and across annular groove 0, and substantially at right angles to stem a, the aperture and groove being above the shield. Instead of being screw-threaded, its stem may be annularly corrugated or barbed and be driven into a hole bored for it in its support. Aperture s is of suitable size to receive a lightning-rod. It also serves to insulate instead of said rod two wires when attached to the insulator at opposite sides of the aperture by winding each wire through and against the side of said aperture and around in the part of said groove connecting with the ends of said side. in it, by which the insulator may be screwed into a telegraph pole or other support. Shield 17 prevents Wetting by rain of the part of stem (0 within the shield or above its bottom.

I claim as my invention- An insulator integral in all its parts, consisting of a stem and a head formed with an annular groove and a direct transverse central hole through the plane of the groove and adapted to receive an ordinary lightning-rod, substantially as described.

THEODORE OREIGHTON.
